nanomem runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 22 Sep 2026.
Memory that knows when a remembered fact has been replaced, not just when it was written.
Nothing serious here today
Today is the operative word: we check nanomem every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
Connect this server
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

}This one needs environment variables set before it will start:
NANOMEM_VAULT (Path to the memory vault file. Defaults to ~/.nanomem/memory.dat.), NANOMEM_PASSWORD (Passphrase to encrypt the vault at rest. Leave UNSET for a plaintext vault; setting it to an empty string is refused rather than silently producing one.).
The author declared them in the registry entry; get the values from the project itself.
